Abstract: When encoding a texture map 1 for use in graphics processing, the texture map is divided into a plurality of equal-sized blocks 2 of texture data elements. Each block 2 of texture data elements is then encoded as a block of texture data 5 that includes a set of integer values to be used to generate a set of base data values for the block, and a set of index values indicating how to use the base data values to generate data values for the texture data elements that the block represents. The integer values and the index values are both encoded in an encoded texture data block using a combination of base-n values, where n is greater than two, and base-2 values. Predefined bit representations are used to represent plural base-n values (n>2) collectively, and the bits of the bit representations representing the base-n values (n>2) are interleaved with bits representing the base-2 values in the encoded texture data block.

Abstract: A tile-based graphics processing pipeline comprising a rasteriser 3, a renderer 6, a tile buffer 10 configured to store rendered fragment data locally to the graphics processing pipeline prior to that data being written out to an external memory, a write out stage 13 configured to write data stored in the tile buffer to an external memory, and a programmable processing stage 14. The programmable processing stage 14 is operable under the control of graphics program instructions to read fragment data stored in the tile buffer 10 on a random access basis, perform a processing operation using the read fragment data, and write the result of the processing operation into the tile buffer 10 or to an external memory.

Abstract: To encode a texture to be used in a graphics processing system, the texture is first downscaled to generate a lower resolution representation of the texture 41. An upscaled version 42 of the lower resolution version of the texture is then compared to the original texture to determine a set of difference values indicating for each texel the difference between the value of the texel in the upscaled version of the texture and in the original texture 43. An encoded texture data block is then generated for each 8×8 block of texels in the original texture 44. Each encoded texture data block contains a base colour value taken from the lower resolution representation of the texture and a set of index values indicating the difference data from the determined set of difference data to be used when decoding the block of texture data to generate the data values to be used for the texture data elements that the block of texture data represents.
